Gepotidacin (GSK2140944)是一种新型的三氮杂苊烯细菌II型拓扑异构酶抑制剂。

Description

Gepotidacin (GSK2140944) is a novel triazaacenaphthylene bacterial type II topoisomerase inhibitor.

In Vitro

Gepotidacin is a novel, first-in-class, triazaacenaphthylene antibacterial that inhibits bacterial DNA gyrase and topoisomerase IV via a unique mechanism and has demonstrated in vitro activity against gram-negative and gram-positive bacterias , including drug-resistant strains, and also targets pathogens associated with other conventional and biothreat infections. The MIC₅₀ and MIC₉₀ for gepotidacin against the 25 N. gonorrhoeae isolates tested are 0.12 and 0.25 μg/mL, respectively^[1]. The gepotidacin MIC₉₀s are as follows (in μg/mL): Streptococcus pyogenes, 0.25; Escherichia coli, 2; Moraxella catarrhalis, ≤0.06; Streptococcus pneumoniae, 0.25; Haemophilus influenzae, 1; Clostridium perfringens, 0.5; and Shigella spp., 1^[2]. Gepotidacin hasin vitroactivity against causative pathogens of acute bacterial skin and skin structure infections (ABSSSIs)^[3].

In Vivo

GSK2140944 MICs are 0.125 to 0.5 mg/L against the six MRSA isolates. ELF penetration ratios range from 1.1 to 1.4. Observed maximal decreases are 1.1 to 3.1 log10 CFU in neutropenic mice. The mean fAUC/MIC ratios required for stasis and 1-log-unit decreases are 59.3 ± 34.6 and 148.4 ± 83.3, respectively.

Animal Administration ^[4]	Mice: For neutropenic pharmacokinetic studies, at 3 h postinoculation (0 h), groups of 48 infected mice are administered GSK2140944 s.c. in single doses of 6.25, 50, or 200 mg/kg. Blood samples are collected from groups of six mice at 5 min and 0.25, 0.5, 1, 1.5, 2, 3, and 4 h postdose for 6.25- or 50-mg/kg doses and 5 min and 0.25, 0.5, 1, 1.5, 2, 4, and 6 h postdose for the 200-mg/kg dose via cardiac puncture^[4].
